This is a preliminary version of a book in progress on the theory of quantum communication.
We adopt an information-theoretic perspective throughout and give a comprehensive …

Taking a quick look at this book, a reader might think: Oh, here comes another book on
quantum computing, quantum information theory, and quantum communications! This may …

Entanglement offers substantial advantages in quantum information processing, but loss
and noise hinder its application in practical scenarios. Although it has been well known for …

Entanglement underpins a variety of quantum-enhanced communication, sensing, and
computing capabilities. Entanglement-assisted communication (EACOMM) leverages …

Quantum hypothesis testing has been greatly advanced for the binary discrimination of two
states, or two channels. In this setting, we already know that quantum entanglement can be …

Achievability in information theory refers to demonstrating a coding strategy that
accomplishes a prescribed performance benchmark for the underlying task. In quantum …

Thermodynamics imposes restrictions on what state transformations are possible. In the
macroscopic limit of asymptotically many independent copies of a state—as for instance in …

We introduce a new quantum decoder based on a variant of the pretty good measurement,
but defined via an alternative matrix quotient. We then use this novel decoder to derive new …

Recently, a coding technique called position-based coding has been used to establish
achievability statements for various kinds of classical communication protocols that use …

Communication is essential for advancing science and technology. Quantum
communication, in particular, benefits from the use of catalysts. During the communication …
